PROCEDE DE TRAITEMENT DE SOLS POLLUES, AU MOYEN D'UN LIANT HYDRAULIQUE A BASE DE CLINKER SULFO-ALUMINEUX ET SON UTILISATION POUR LA STABILISATION DE SOLS POLLUES
A process for treating polluted soils, in particular soils with a leachable fraction greater than 0.4%, wherein the leachable fraction contains predominantly anions, in particular sulfate ions, and/or heavy metals, includes mixing the soil with a sulfoaluminate-clinker-based hydraulic binder, in soil/binder weight proportions of between 1 and 40 parts of binder per 100 parts of soil, the sulfoaluminate clinker containing more than 50% by weight of ye'elimite C4A3S phase, less than 15% by weight of belite C2S phase, and from 1% to 5% by weight of free lime CaO. The process is used for stabilizing soils in situ or before dumping, soils polluted in particular with sulfate anions and/or heavy metal cations.
